Processing of live multimedia content and/or data streams over a communication network

ABSTRACT

A method and associated device for streaming multimedia data over a communication network. Data associated with live multimedia content is received. Portions of the data are processed into data chunks. Each data chunk is associated with the live multimedia content. A request is received for the live multimedia content. The data chunks associated with the live multimedia content are transmitted over the communication network, in response to the request for the live multimedia content.

The present invention claims priority to U.S. Provisional No. 62/165,515, filed on May 22, 2015, which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to content (e.g., data) delivery over a communication network, and more particularly, to processing live multimedia content and/or data streams to be used in live, buffered, and fully recorded contexts.

BACKGROUND

Streaming multimedia content and/or data live over a communication network, especially when large scales of users may subscribe to and request content and/or data, presents a number of obstacles such as network outages, connectivity issues, unusual ingest formats, temporary breaks in stream, and the like. Robust content delivery techniques that are scalable, resilient against network or device glitches, breaks in a broadcast stream, connectivity issues, and the like, while also minimizing errors in underlying content such as unsynchronized audio and visual elements in video, shortened recordings (cut off at the end or beginning), recordings split into multiple files, and the like, exist in the context of live streaming, but do not also address such errors in connection with buffering of such streams for later, limited time-delayed (DVR, or digital video recording) access or in connection with full recording for later VOD (video-on-demand) access.

Further, recording multimedia data in traditional content delivery systems typically requires a broadcast to end (e.g., terminate) before any recording of the broadcast can be accessed or manipulated, which is especially bothersome in the case of very long broadcasts. For example, highlight videos cannot be created while a live-streamed sports match is still going. The broadcaster, using a traditional content delivery system, either has to stop and restart ingesting, which risks losing portions of the broadcast, or wait until the end of the broadcast for editing, which detracts from the immediacy of live video.

Moreover, traditional content delivery systems create and store differently formatted content and/or data for each specific supported client format (Mac, Windows, Android, iOS, and the like), and often must store such content and/or data in chunks of multiple sizes or lengths based on storage optimization considerations or format requirements (for example, three-second long video chunks in a proprietary format optimized for storage, and five-second long video chunks in MPEG-TS format for use with iOS clients), which takes up computing resources for transcoding as well as storage space, since multiple versions of the same content must be created and stored. For example, in certain instances, broadcasters may create/store multiple versions of the same VOD content with different QoS parameters (e.g., bit rates, etc.) specific to a type of requesting client device in order to properly serve the requesting client device; e.g., a mobile device may have different QoS parameters than a large television.

From a service provider point of view, merely introducing a separate recording architecture (e.g., limited time-delayed (DVR, or digital video recording) access, full recording for later VOD (video-on-demand), etc.) to a live content delivery system is not ideal. For example, introducing a separate recording architecture to a live streaming system, including buffering and/or recording architectures, may result in increasing a number of possible errors.

SUMMARY

The present invention provides a method, and associated system, device and computer program product, for streaming multimedia data over a communication network. One or more processors receive data associated with live multimedia content. The one or more processors process portions of the received data into data chunks. The one or more processors associate each data chunk with the live multimedia content. The one or more processors receive a request for the live multimedia content. The one or more processors transmit the data chunks associated with the live multimedia content over the communication network, in response to the request for the live multimedia content.

The present invention provides techniques to unify multimedia processes (e.g., ingest, store, serve, etc.) for streaming multimedia content, including but not limited to live content such as a live broadcast, buffered content such as digital video recording (DVR), recorded content such as video on demand (VOD), and the like. These techniques particularly blur the line between live, buffered, and recorded content delivery and overcome obstacles presented by conventional multimedia data streaming (e.g., glitches during a live stream, processing or transforming multimedia content into different formats, etc.) and minimize errors in underlying content (e.g., unsynchronized audio and visual elements in video, shortened recordings (e.g., cut off at the end, cut off at the beginning, etc.), recordings split into multiple files, etc.). Moreover, the techniques of the present invention facilitate and enable dynamic editing (splicing different portions together, combining portions with other existing multimedia content and/or data, adding data to different portions, highlighting portions, and the like) of multimedia content without waiting for completion of a streaming transmission or waiting for multimedia content to be uploaded to a video management system. Further, the system architecture of the present invention avoids increasing the number of possible errors arising from bolting on a separate buffering and/or recording architecture to the content delivery system.

DETAILED DESCRIPTION

FIG. 1 illustrates an example communication network 100, in accordance with embodiments of the present invention. Communication network 100 illustratively shows content providers 105 as well as a geographically distributed collection of sub-networks, including various Content Delivery Networks (CDNs) (e.g., UCDN 110, Regular CDN 115, ISP-CDN 120, and eCDN 125), corresponding Point of Presence (PoP) servers (e.g., PoP s 111, PoPs 116, PoPs 121, and PoPs 126), and two Internet Service Provider (ISP) networks (e.g., ISP 130 and ISP 135), and client devices 140 (e.g., customers, subscribers, etc.).

As described above, CDNs provide a valuable resource for content providers to meet ever increasing demand for digital content over corresponding communication networks. CDNs, such as those shown in communication 100, locally store and serve requested content to end users (e.g., at client devices 140). For example, operatively, content providers 105 (e.g., media companies, e-commerce vendors, etc.) contract with CDN operators (e.g., operators of CDN 110, 115, 120, 125, etc.) to deliver the content providers' content to a requesting end-user (e.g., client devices 140). The CDN provider, in turn, contracts with one or more ISPs (e.g., ISP 130, 135, etc.), carriers, and network operators to hosting the content providers' servers in their (i.e., the ISPs, carriers, network operators) data centers. In this fashion, CDNs improve performance, availability for content, and also offload network traffic served directly from the content provider's origin infrastructure, resulting in potential cost savings for the content provider.

Requests for content or data from client devices 140 are typically directed to network nodes or devices in an “optimal” fashion. Optimal may be measured by choosing locations, relative to a requesting client device, that is the fewest hops to a CDN, providing lower network latency (e.g., a least number of network seconds away between a requesting client and a corresponding CDN), and the like. Various optimizing logic chooses which metric will be used to base a decision upon. For example, even though a client device or destination node may be physically closest to a CDN or source node, the network latency (e.g., in network seconds) can be high. Similarly, a client device may be located at a least number of hops away from a CDN (in close network proximity), but the client device may still be very far (in geo-proximity) from the CDN, which can also result in a high network latency. Additional optimal characteristics can also include a highest availability of the CDN in terms of server performance (both current and historical), so as to optimize delivery across local networks. Alternatively, optimal can be measured as cost, whereby locations that are least expensive to server content can be a factor in choosing the network. These various metrics may be balanced to provide optimal performance for content delivery to client devices.

Still referring to FIG. 1, PoPs 111, 116, 121 and 126, sometimes referred to as “edges” or “edge network nodes/devices”, facilitate content transfer from respective CDNs to ISP 130 and/or ISP 135. Notably, PoPs typically represent the closest “edge” from the perspective of an end-user or client device relative to CDN assets or content. CDNs 110, 115, 120, and 125 provide services to corresponding PoPs depending on, for example, geographic coverage.

When a client device requests content from one of content providers 105, the client device is re-directed to a local CDN, such as ISP-CDN 120. For example, the request is routed through the client device's ISP network (e.g., ISP 135), corresponding PoPs, and onward to a corresponding CDN. Various other network devices or nodes facilitate this process (e.g., routers, switches, Domain Name Service (DNS) nodes, and the like); however, for purposes of simplicity, such other devices or nodes are not shown. A CDN such as ISP-CDN 120 receives the request from the client device and, in response, provides the content to the client device (again, through corresponding PoP(s), ISP(s), etc.).

Notably, communication network 100 is shown for purposes of simplicity, not limitation. For example, as is appreciated by those skilled in the art, the devices and networks shown are interconnected by various communication links (e.g., wired, wireless, etc.) and segments for transporting data, which further support various methods for communication and communication protocols. Further, the networks and sub-networks shown in FIG. 1 can represent many different types of networks (e.g., ranging from local area networks (LANs) to wide area networks (WANs)). It is appreciated that any number of devices, networks, links, etc. may be used in the communication network 100 and further, each of the sub-networks can include or exclude any number of devices or nodes (e.g., switches, routers, etc.), as appropriate.

FIG. 2 illustrates a schematic block diagram of a chunk processing architecture 200, in accordance with embodiments of the present invention. Chunk processing architecture 200 provides a unified multimedia process (e.g., ingest, store, serve, etc.) for streaming multimedia content (e.g., live broadcast, DVR, VOD, etc.). As shown, chunk processing architecture 200 processes (e.g., ingests, stores, delivers/serves, etc.) multimedia content, and provides multimedia content as a streaming transmission to one or more Content Delivery Networks (e.g., CDN(s) 110, 115 shown in FIG. 1). Chunk processing architecture 200 includes an ingest server 205, a cache 210 to temporarily store one or more data chunks, a database 215 for long term storage, and a chunk server 220.

Operationally, ingest server 205 receives multimedia content from content providers. As discussed above, the multimedia content can include, for example, live broadcast content. Ingest server 205 may execute a chunk application to process (e.g., break up) the streaming multimedia content into smaller data chunks. Data chunks, as used herein, refer to a fragment of data used in various multimedia formats (e.g., flash video, (FLV), MPEG4, PNG, IFF, MP3, AVI, etc.). The data chunks may be stored in cache 210 (e.g., local to ingest server 205) for short term storage and in database 215 for long term storage (e.g., external storage, distributed storage, etc.). When chunk server 220 receives multimedia content requests from CDNs (which receive requests from client devices), chunk server 220 converts data chunks corresponding to the request into an appropriate format for the client device (e.g., FLV, etc.), and transmits the corresponding data chunks to the CDNs for delivery to the client device.

The data chunks may be stored in a universal or unified format to facilitate efficient processing by chunk server 220 when, for example, chunk server 220 converts data chunks into an appropriate format for respective client devices. In addition, in certain embodiments, ingest server 205 and/or chunk server 220 are configured to change a chunk size on demand for any output format. Significantly, changing the chunk size on demand for output formats divorces storage size requirements from transmission and/or streaming size requirements. For example, a stored chunk size can include three second long chunks (e.g., in the universal or unified format), while streaming chunks for HTTP (e.g., MPEG TS for iOS transmission, etc.) can include five second long chunks. Accordingly, chunk server 220 can convert such three second long chunks to the output format of five second long chunks on demand. Notably, the data chunks may be associated with a particular multimedia identifier (e.g., a broadcast) such as an index file, which may be specified in a request for content. Further, each of the data chunks for a particular index file may be indexed or otherwise associated with a time relative to the multimedia content.

Ingest server 205 also processes multimedia content from video content in the same fashion (e.g., into data chunks) as live broadcast content, which obviates the need for additional recording devices. In this fashion, multimedia content for either video or live broadcast is processed and delivered in the same way (e.g., requesting an appropriate subset of data chunks for an index file). Further, creating a video on demand (VOD) is as easy as specifying the data chunks in an index file. Chunk processing architecture 200 also ensures that any processed VOD is an exact replica of a live stream, since the data chunks for the VOD includes the same data chunks as the live stream. Additionally, much less storage space is needed by storing only one set of data chunks for later format conversion instead of storing multiple videos with various formats. In this fashion, specific video formats can be created dynamically, in real-time and on-demand, thus preserving resources (e.g., the processing is only performed when requested). Moreover, a late-joining viewer does not have to start watching a multimedia content stream mid-live or even wait for the end of a live stream broadcast and subsequent upload of (an edited) recording. Instead, multimedia data chunks for the live stream broadcast index file can be accessed and viewed on delay similar to DVR recordings. Thus, chunk processing architecture 200 blurs the lines between live, DVR and video-on-demand content.

FIG. 3 illustrates an example communication network 300, in accordance with embodiments of the present invention. The communication network 300 includes content providers 105, chunk processing architecture 200, UCDN 110, regular CDN 115, corresponding PoPs 111 and 116, ISP 130 and client devices 140. As shown, chunk processing architecture is positioned between the CDNs (UCDN 110 and regular CDN 115) and content providers 105.

Chunk processing architecture 200 may be deployed as a software framework instantiated as a dynamic, request based response. That is, chunk processing architecture 200 can be incorporated within application servers in the content networks and/or the CDN networks. When a CDN and/or content provider receives a request for multimedia content, the CDN and/or content provider can instantiate the resources required for the chunk processing architecture 200 to process the requested multimedia data as data chunks, as discussed above. In this fashion, the chunk processing architecture 200 is scalable and can be instantiated multiple times as a distributed processing architecture to process large volumes of requests for multimedia content.

FIG. 4 illustrates an example server device 400 in the communication network 300 shown in FIG. 3, in accordance with embodiments of the present invention. The communication network 300 may be used with one or more embodiments described herein, (e.g., a device employing chunk process or chunk processing architecture 200). Server device 400 includes one or more network interfaces 410, at least one processor 420 (e.g., a hardware controller/processor), and a memory 440 interconnected by a system bus 450.

Network interface(s) 410 contain the mechanical, electrical, and signaling circuitry for communicating data over physical and/or wireless links coupled to one or more CDNs, content provider networks, and the like. Network interfaces 410 may be configured to transmit and/or receive data using a variety of different communication protocols, including, inter alia, TCP/IP, UDP, wireless protocols (e.g., IEEE Std. 802.15.4, WiFi, Bluetooth®), Ethernet, powerline communication (PLC) protocols, Real Time Messaging Protocols (RTMP), a Real Time Streaming Protocols (RTSP), a Hypertext Transfer Protocols (HTTP), and HTTP Live Streaming (HLS) Protocols, etc.

Memory 440 comprises a plurality of storage locations that are addressable by the processor 420 and network interfaces 410 for storing software programs and data structures associated with the embodiments described herein. Certain embodiments of server device 400 may include limited memory or no memory (e.g., no memory for storage other than for programs/processes operating on the server device 400). Processor 420 includes necessary elements or logic adapted to execute the software programs and manipulate data structures 445.

An operating system 442, portions of which are typically resident in memory 440 and executed by the processor 420, functionally organizes the device by, inter alia, invoking operations in support of software processes and/or services executing on the server device 400. For example, these software processes and/or services may comprise chunk process/services 444. It will be apparent to those skilled in the art that other processor and memory types, including various computer-readable media, may be used to store and execute program instructions pertaining to the techniques described herein. Also, while the description illustrates various processes, it is expressly contemplated that various processes may be embodied as modules configured to operate in accordance with the techniques herein (e.g., according to the functionality of a similar process).

Illustratively, the techniques described herein may be performed by hardware, software, and/or firmware, such as in accordance with the chunk process 444, which may contain computer executable instructions executed by the processor 420 (or independent processor of interfaces 410) to perform functions relating to the techniques described herein.

Chunk process 444, when employed by server device 400, operatively processes multimedia content, including ingesting, breaking multimedia content into data chunks, indexing, storing, and the like. For example, as discussed in greater detail above, chunk process 444 operates to achieve chunk processing architecture 200.

The techniques described herein, therefore, provide for processing multimedia content, particularly for both live streaming broadcasts as well as buffered or recorded video content, for content and/or data transfer networks, including CDNs. These techniques provide for simplified, but efficient multimedia processing using a chunk architecture. Such techniques can be employed by, for example, application servers associated with content and/or data transfer networks and may further be instantiated on-demand.

While there have been shown and described illustrative embodiments for processing multimedia content, it is to be understood that various other adaptations and modifications may be made within the spirit and scope of the embodiments herein. For example, the embodiments have been shown and described herein with relation to particular CDNs, ISP networks, etc. However, the embodiments in their broader sense are not as limited, and may, in fact, be used with any number of networks, client devices, and the like.

The foregoing description has been directed to specific embodiments. It will be apparent, however, that other variations and modifications may be made to the described embodiments, with the attainment of some or all of their advantages. For instance, it is expressly contemplated that the components and/or elements described herein can be implemented as software being stored on a tangible (non-transitory) computer-readable medium, devices, and memories (e.g., disks/CDs/RAM/EEPROM/etc.) having program instructions executing on a computer, hardware, firmware, or a combination thereof. Further, methods describing the various functions and techniques described herein can be implemented using computer-executable instructions that are stored or otherwise available from computer readable media.
